Glass Level Gauge

The main element of the glass level gauge is the gauge body. Incorporated into this level gauge body are the liquid channel (if necessary the heating channel) and the seating faces for the chambered seals and sight glasses.

Onto the level gauge body are mounted, or are already integrated, the valve heads and process connections. Drain or vent are also possible.

The glasses and/or mica shields as well as the seals are fitted, secured and sealed with the aid of U-bolts and covers or pressure frames. Glasses from borosilicate glass in accordance with DIN 7081 are used.

For steam, the glasses can be used up to 243 °C, with mica design to 300 °C. For other media, temperatures up to 300 °C are possible, in special cases up to 374 °C. The use of mica is needed for specific applications.

Sight Glass vs. Magnetic Level Gauge

Local level gauge is an important measurement for many process control applications. It provides a reliable way to confirm the level gauge height. It allows a way to check and calibrate level transmitters. It can be used to temporarily and manually control the liquid level gauge when the normal control systems are down. And it offers a redundant technology to measure level gauge.

Two technologies typically used for local indication are armored sight glass and magnetic level gauge.

Armored sight glass usually consists of two armored castings that sandwich a piece of glass, allowing direct visibility of the liquid level gauge. A magnetic level gauge is typically made up of a float containing a magnet that follows the liquid level gauge inside of a chamber. The position of the float inside the chamber is indicated outside by dual-colored flappers embedded with magnets. As the magnet inside the float interacts with the magnets on the flapper outside of the chamber, the flapper turns and changes color to indicate level gauge.

When deciding which technology to use, it is important to look at the long-term cost of ownership rather than just the upfront cost of the unit. Sight glass technology typically has a lower upfront cost than an MLI; however, an MLI has many benefits during installation and normal operations that result in a lower total cost of ownership in the long run.

The four key ways — enhanced safety, maintenance, increased visibility and simplified installation — in which an MLI will actually reduce overall cost over time and improve functionality are discussed in this article. We will also go through an example of comparing the total cost of ownership of a sight glass to that of an MLI over a five-year period. A lot of these values are estimates and will vary greatly on changing applications and from plant to plant. In this example, we will use a 3’ indication length and assume our initial upfront cost of the sight glass is $450 while our MLI has a starting cost of $2,200.

Effective Servo Tank Gauge

Intelligent servo tank gauge is a combination of site conditions of the petroleum, chemical, metallurgy, medicine, food and other industries, developed with independent intellectual property rights of a new generation of intelligent level measurement instruments. Because of this instrument in the measurement method and the traditional methods of measurement makes it totally different from the measurement accuracy is the world’s all level measurement instrument can not be compared. Intelligent servo tank gauge can be installed through the top of the tank meets the requirements of a single or multiple measurements. The servo tank gauge with my plant tank intelligent management system supporting the use of tanks in the region can be for all tank level, temperature, pressure and other centralized measurement, control, display and print reports, and according to the above the implementation of automated metering tank parameters and data upload, thus truly a “convenience”, “intuitive.” Modernized tank farm of intelligent management.

Scope: versatile measurement and standard output signals as well as the integration of lightweight design makes Intelligent servo tank gauge can be widely used in various areas to be measured.

Chemical industry: in the field of chemical industry, a variety of anti-corrosion material shell of arbitrary choice, to meet the chemical industry in different media level, interface and other measurement requirements.

Food industry: in the beverage industry, a large number of liquid products throughout the production process, an accurate measurement of the liquid level is directly related to the cost of production control and production management.

Power industry: fuel, accurate measurement of oil and large boiler water level is directly related to the production of safe and accurate management.

How it works:

Servo tank gauge measurement is based on the principle of buoyancy balance and design. Fixed within the magnet wheel motor drive with precision-machined drum (ie outside the magnet wheel) to complete the magnetic coupling between. So that the drum and the drive motor is formed synchronously rotated, the meter housing is completely isolated from the magnet between the inner wheel and the drum (outer magnet wheel), so that the measured liquid chamber and the electrical part is completely isolated and meet proof requirements, uniform measurement wire neatly arranged on the drum. The float was sent to the tank by measuring the wire. When the tank level (interface or specific gravity) changes due to the weight of the float level varies with changes, changes in the weight of the float makes the drum (outer magnet wheel) is formed between the inner magnet wheel and coupling poor. After the signal is sent to the microprocessor to calculate judge to issue control instructions to the servo motor, making the tank with the liquid level of the float always changes.

The Requirements of Full Containment Storage Tank gauge for LPG LNG – Long Term Storage

Full containment tank gauge for LPG LNG are large and complex structures with a typical capacity of up to 200,000 m3.

They include an inner liquid containment steel tank gauge for LPG LNG, an outer concrete (or steel) tank for secondary containment control, and thermal insulation between the two to minimize liquid boil-off.

The planning, design, and construction of such technically advanced tank gauge for LPG LNG requires significant investment, and payback times can be lengthy. For this reason, tank gauge for LPG LNG farm operators need to implement accurate and reliable tank gauging systems that will help to minimize operating and maintenance costs, thereby enabling a quicker return on investment.

Maximum Level Gauges

The maximum level guge is a cost-effective measuring device that indicates the maximum water level gauge by tidal waves or other level fluctuations over a color marking. It is based on the simple principle of color marking. The threshold level gauge is used for preservation of evidence and provides accurate data for later post-processing of flood events.

Rugged cylinders made of Plexiglas and a fiberglass reinforced plastic measuring rod with easy to read E-scale in cm graduation.

Self-adhesive, transparent ribbon to display the highest water level gauge. To change the ribbon, you need to solve only one single screw.

Simple operation: water thaz rises in the cylinder, completely washes out the color to the respective water level gauge.

Clear result: A sharp dividing line between colored and colorless area enables accurate reading of the maximum water level gauge.

Unaffected by waves and debris: The straining device acts as filter for coarse dirt and acts as a damping device preventing influence by wash of waves in the measuring cylinder.
